4 Claims.

This invention relates to double sash constructions, such as are used in railway cars, buses, and other structures, where it is necessary or desirable to use a moisture-absorbing agent in the space between the glass panes of the double sash, for'preventing clouding of the glass, due to differences of temperatures on the inside and outside of the window of the car, bus or other structure; and has for its object a particularly simple construction by 'Jhich a container for a moisture-absorbing agent is assembled with the sash structure and supported between the glass panes, and further by which-it is readily accessible for the purpose of renewing the mois- 1 .ture-absorbing material.

The invention consists in the novel features and in the combinations andconstructions hereinafter. set forth and claimed.

In describing this invention, reference is had to the accompanying drawing, which is a fragmentary isometric view on an enlarged scale of the double sash window structure embodying this invention.

The window structure is practically the same as that shown in mypending application, Serial Number 185,565, filed January 18, 1938, of which application this is a division.

The invention comprises a receptacle for a moisture-absorbing agent, as activated alumina,

extending into the space between the glass panes of the double sash, and being a separate part from the sash structure and readily accessible upon removing of one of the glass panels.

In the illustrated embodiment of the invention,

5 the sash frame is formed in two sections, one

section for each glass panel and the receptable is carried by one of the sections and its companion glass panel and removable therewith and also removable therefrom, so that in removing broken glass pane, the receptacle may be applied to the new glass pane and its sash frame section.

l designates a. window frame formed with a,

channel 2 for receiving the sash element, the channel having a removable side flange or strip 45 3, which is clamped against the window frame to clamp the sash in the channel in any suitable manner, as by screws, as shown at 4. The sash frame element here illustrated includes two sections 5, 6, one for each glass'panel 1, 8, and the 50 sections here shown are tirelike members of resilient material, as rubber, each formed with a groove 9 for receiving themargin of the glass pane 1 or 8. When the flange or strip 3 is tightened by means of the screws 4, it compresses 55 the resilient section 5 against the other and tightly seals the sections of the double sash together and in the channel 2, and hence, tightly seals the air space between the glass panes l, 8. The, section 6, which is adjacent the flange or strip 3, is preferably on the inner side of the car, bus or other structure, and is readily demountable, either for the purpose of washing the windows, replacing broken glass, or renewing the moisture-absorbing material. Upon relengthwise channel and has a base flange ll forming an extension of one of the side walls of the channel, and this side wall of the channel and the base flange ll lies flatwise on the glass pane 8 and extends into the groove 9 of the sec- 25 tion 6 and interlocks therein, it being shown as formed with an angular flange l2 hooking around theedge of the glass 8. It preferably suspended from the upper edge of the glass 8 or from the upper run or top rail of the tirelike 30 member 6 close to the top of the sash, in order to be concealed by the curtain for the window,

it being understood that the curtain, when in its completely raised position, laps the sash far enough to cover the receptacle H). The wall of the channel 10 remote from the other glass 1 is spaced apart therefrom at l3 to form an air circulating space.

In initially assembling the sash with the receptacle Ill, the receptacle I0 is placed in juxtaposition to the glass 8 with the flange l2 extending around the edge of the glass, and then the tirelike member 6 placed in position. When it is necessary to renew the moisture-absorbing material or activated alumina in the receptable 5 III, the flange 3 is demounted, and the section 6 with its glass panel 8 removed, this giving access to the channel l0, so that the moisture-absorbing material may be removed and replaced. In case the glass 8 becomes broken, the flange 3 may be removed and the tirelike member with the splinters or fragments of glass therein removed and the receptacle applied to a new glass, and the new glass mounted in the tirelike member and the assembled tirelike member 6 and new glass 8 replaced in the window frame. Heretofore, channels for activated alumina have been formed in the sash frame either beyond the edge -of the glass pane, betweenor integral with one of the sash sections on the inner side thereof where it abuts against the other section, so that the sections are not duplicates, or'a special cavity has been provided for the activated alumina entirely outside of the sash, or in the corner portions thereof, which recess communicates with the space between the sash through ducts.

By the construction here shown, great economy and simplicity result in double sash constructions in which means is provided for receiving a moisture-absorbing material.

What I claim is:

1. In -a window construction, the combination with a window frame, a double sash mounted in the window frame and including a sash frame elementformed with grooves for receiving the margins of spaced apart glass panes; of a receptacle for receiving a moisture-absorbing agent located in the space between the glass panes and having a portion extending into one of the grooves and hooking over the edge of the glass pane in said groove.

2. In a window construction, the combination with a window frame, a double sash mounted in the window frame including a sash frame element formed with grooves for receiving the margins of the spaced apart glass panes; of a receptacle for receiving a moisture-absorbing agent separable from the frame element and extending into the space between the glass panes,

the frame element being so constructed that one of the glass panels is removable independently of the other panel and the receptacle having a base coacting with the frame element and said demountable glass panel.

3. In a window construction, the combination with a window frame, a double sash mounted in the window frame including a sash frame element formed with grooves for' receiving the margins of the spaced apart glass panes, said elearound each glass pane, and each section being formed with one of said grooves, and means for clamping the sections against each other; of a receptable for receiving a moisture-absorbing agent separable from the sections and extending into the space and located entirely between the glass panes and having a base flange coacting with and separable from the frame element.

4. In a window construction, the combination with a window frame, a double sash mounted in the window frame including a sash frame element formed with grooves for receiving the -ment including two separable sections, one
